I've this annoying problem. When I suspend, the suspension seems to work fine. But when I try to resume, the screen stay black, with neither retro-illumination nor cursor, and without the possibility to press any key.

Hello ryszd. Your machine has two graphics processors running shared memory with the cpu. This may make suspend problems more difficult to resolve.Can you please confirm how much physical memory you have ? And can you please also try to suspend the machine, then listen to hear if the CPU fan is still running ?Also have you checked the logs for any suspend or resume errors ?

I have the same problem running Cinnamon on my Acer Aspire 5553G, it suspends normally (everything is off except for a blinking light indicating sleep), after waking it up the fan runs, the monitor backlight turns on (but still black), other notification lights are on just like under normal operation, except that there's nothing on the screen. Now I must turn it off if I'm not using it for a short while.

The software is LMDE 14 ("Nadia"), XFCE version. Except for the flaw mentioned above this works clean right out of the box on my hardware. This isn't true for certain other distributions and therefore deserves my special appreciation (and hopefully not only mine).

--- begin of a side noteAs a side note I would like to mention that the ONLY distribution which I have tried out that handles the suspend/resume procedure more or less successfully is Joli OS 1.2 (Ubuntu-based). Apparently they made a lot of special adaptations for netbooks, and for the Intel Atom in particular. The wakeup/resume mechanism isn't reliable, though, as in about 30% of all cases I have to press <Ctrl><Alt>F2 followed by <Ctrl><Alt>F1 in order to see the "Unlock Screen" dialog. The LCD backlight is always turned on immediately, however, as soon as I hit a key for wakeup. The F2 key mentioned above may also be any other F-key except F1 (no wonder with X-windows).

I haven't had (and will not have in the near future) the time to investigate what Joli OS does and LMDE Xfce doesn't do.

I am striving to get away from Joli because sometimes it behaves annoyingly (hangs for tens of seconds). It doesn't really crash, though, and therefore deserves to be called 'quite stable'.--- end of the side note
